Regarding cold medicine, although Lan Shu didn't know the detailed formula, she had something to say.

"Your cold medicine should be researched based on the constitution and dosage of adults, right? Is it possible to produce a cold medicine for children based on the medicines for adults?"

"Children are very vulnerable, especially those under two years old. If they get sick and use adult drugs, they will inevitably have problems."

The dosage and ingredients of medications for adults and children should be different.

In the early stages of many drug research, adult dosage was used as the standard, and children's drugs gradually began to appear only one to twenty years later.

Before the emergence of children's medicines, Lan Shu had read some reports and knew that some children under the age of two or three had convulsions, cardiovascular, respiratory, and neurological side effects after taking cold medicines.

Because cold medicines for adults are compound medicines, which contain a variety of active ingredients. Although the medicines are quick to treat symptoms, if they are used by children who are too young, they will cause a lot of burden on the liver and kidneys, and in severe cases, they may even cause the death of young children!

Therefore, she hopes that Xiaobai and his research team will pay attention to this situation, whether it is for the sake of sick children who will take medicine in the future, or for the future reputation of researchers like Xiaobai.

Xiaobai rarely sees Lan Shu showing such a cautious expression.

Although he didn't know why Lan Shu was suddenly so concerned about drug research, it was undeniable that what Lan Shu said did make sense.

So he nodded, "I understand, I will raise the matter of children's cold medicine with the seniors and seniors."

After speaking, he added, "Not only this time for cold medicine, but also for various drug studies that I will participate in in the future, I will take the medication of children into consideration."

With Xiaobai's words, Lan Shu finally breathed a sigh of relief and felt at ease.

After finishing talking about Xiaobai's work, Lan Shu remembered to give Xiaobai the buns she brought from her home.

Putting the lunch box into Xiaobai's hand, Lan Shu said, "The buns I brought you are stuffed with meat, one bite at a time."

After speaking, her tone was a little regretful.

"Although I wrapped a towel on the lunch box to keep it warm, it is probably getting cold by now. You can take it to the canteen and see if the kitchen can help you heat it up before eating."

Seeing Lan Shu treat him as always, Xiaobai's previous rejection mood was quickly diluted by this pure concern——

He nodded and replied, "Okay."

This time when the two met, they both had a tacit understanding and did not mention anything other than friendship. The relationship seemed to be back to the past, as harmonious as ever.

Xiaobai had lab tasks in the afternoon, so Lan Shu didn't stay too long.

After meeting people and delivering things, she would wave goodbye to Xiaobai.

But Xiaobai still had something to say.

"Lanshu, I will be on summer vacation in more than half a month. Then I want to go to Qingyang County... to visit grandma."

While Xiaobai was talking, his eyes never left Lan Shu's eyes.

In previous years, he would indeed take time to visit his grandma during his vacation and stay in Qingyang County for a few days.

But this time he wants to go to Qingyang County not only because of his grandma, but also to find clues about his original murder and to get closer to Lan Shu.

Xiaobai originally thought that getting close to Lan Shu after confessing his love might cause Lan Shu to feel alienated from him.

But he found that Lan Shu did not hesitate at all after hearing the news——

"Okay~ You can also go to the toilet paper factory at that time. The development of the factory is very different from before!"

After hearing this answer, Xiaobai could finally feel relieved, but at the same time he also sighed a little.

The relationship between him and Lan Shu has returned to its past, but such pure friendship is also a manifestation of Lan Shu's rejection of him...

…

This time Lan Shu stayed in Kyoto for a total of half a month. In mid-June, she planned to leave Kyoto and return to Qingyang County.

Before going back, Lan Weicheng and Xu Shan took a day off and went to the mansion Lan Shu bought on Chang'an Street.

The two of them came empty-handed. Lan Weicheng was carrying a lot of ingredients, including fish, meat, eggs, and vegetables.

Xu Shan was holding a large flat square box in her hand. After opening it, Lan Shu discovered that there was an old-fashioned cream cake inside!

It has been almost a year since Lan Shu came to this world, and this was the first time she saw a cake. Looking at the words "Happy Birthday" written thinly on the translucent red butterscotch, Lan Shu was stunned and realized.

"Today is my birthday?"

"Yes, Shushu, I remember very clearly that twenty years ago today, I gave birth to you in the hospital in Qingyang County."

Xu Shan said, the expression on her face was obviously lost in memories of the past.

"Twenty years..."

Lan Shu took a breath. She is now twenty years old...

Plus today, Lan Shu has experienced turning twenty twice, but this is her first birthday.

She remembered her past self. Because she was an orphan, she didn't know when her birthday was.

So she has celebrated Children's Day every year as her birthday since she was a child.

When I was a child in the orphanage, I could get sweet candies on Children’s Day.

That day was the happiest day for her.

After growing up, she was busy with life and study every day, and she had no free time to think about her birthday.

But today, in this era that should be strange to her, she had the experience of celebrating her birthday.

Lunch was cooked by Xu Shan and Lan Weicheng. At the dinner table, Lan Shu made a wish on the cake.

Compared with the various shortcomings in her previous life, now she wants to stay in this world forever...

…

The next day after her birthday, Lan Shu got on the train and left Kyoto.

Back in Qingyang County, Lan Shu still went to two factories to check the situation.

The sanitary paper factory's small-pack paper assembly line has been put into production. When the portable small-pack paper was delivered to various places in the factory the day before yesterday, some were also taken out for trial sales first.

As for the advertising of small packet paper, Deputy Director Zhu has already communicated with the Linjiang City newspaper and is planning to check the situation with the last issue of advertising this weekend.

When Lan Shu was not in the factory before, Deputy Director Zhu arranged everything in the factory properly.

On the other side, Yunshu Garment Factory.

The development of the garment factory is proceeding steadily.

After Lan Shu arrived at the factory, she first went to see Secretary Tang and inquired about the recent work of the new financial officer in the factory.

Pan Gong, the new finance manager, has many years of work experience, so after taking over the financial work of the garment factory, it only took him a few days to get familiar with it and get started immediately.

In the half month since Lan Shu left, Pan Finance has calculated every account in the factory.

Different from the previous monthly settlement of accounts, now the weekly import and export and profit status are clearly displayed in Pan Finance's tables.

This is a sign of excellent professional ability!
